Ads can be blocked:
By website domain or mobile app Bundle ID: add domains or Bundle IDs for ads that should not be displayed in the app.
By phone number: add phone numbers related to ads that should not be served on the mobile platform (for example, +7 (495) 739-70-00). Blocking by phone number is only used for ads that do not link to a site or a page in the App Store.
Specify comma-separated domains, Bundle IDs, or phone numbers in the New blockings field and click Add. All changes to settings will automatically take effect 30 minutes after saving them.
